A Grinding Trajectory Accurate Calculation Method for Circular-arc End Mill Flanks Based on Contact Area Adaptive Adjustment
In order to ensure the machining accuracy of circular-arc end mill flanks,a grinding trajectory accurate calculation method for circular-arc end mill flanks was proposed based on contact area adaptive adjustment.Firstly,the mathematical model of the flank was constructed through struc-tural feature decomposition of the circular-arc end mill.Then,by calculating the grinding contact area between the grinding wheel and the flank,the grinding wheel posture was adaptively corrected to a-void grinding interference,which realized the accuracy and consistency of flank geometric parameter control and ensured the smooth connection of the curved surfaces.Finally,based on the implement of VC++platform algorithm module,the effectiveness of the proposed algorithm was verified by machi-ning simulation and grinding experiments.
